  1. Near Detector Electronics Status Status Production Issues Peter Shanahan FNAL MINOS Collaboration Meeting June 13, 2003

  3. Near Detector Electronics Status • Schedule Status (BCWP/Total Budget): • 88% (April 03) • All WBS 2.3.1 system components are in production • Problems with MENU startup • All Printed Circuit boards in Assembly phase (or done…) • Thorough checkout in progress • All power supplies received/ crates in progress • WBS 2.3.6 • Auxillary systems (timing) • Minder Timing Modules, Clock Fanouts, Master Clock Controller done • Redesign of VME Timing Module for flexibility

  4. MENU Production • Front-end daughter card • Supports and reads out QIE • Stores digital data in pipeline • 9328 in system • 1440 plus spares required for CALDET

  5. MENU Production Problems • Sporadic production startup: • Fabrication • Solder on gold contacts – not noticed until fabrication began. • Vendor has accepted responsibility: inspection+new boards • Vendor inspection insufficient (no microscope on QC line!) • Assembly • Incorrect 1st articles • Overheated “burn-in” by vendor on 200 boards • Poorly tuned initial automated optical inspection by vendor • Wrong solder flux on several hundred boards • All problems addressed by vendor • Production has finally reached steady rate with consistent quality • Much effort on 14th floor: Lou Dal Monte, Merle Watson, Charlie Nelson

  6. MENU Good News • 5000 boards in hand • Checkout rate of boards with no acute problems is >90% • Assumed 67% in checkout schedule • Thorough checkout of all MENU functionality • IIT Undergrads for Checkout • Resident at FNAL for 5 weeks • Will later take test-stand to IIT • Very helpful in meeting CALDET schedule • Long-term production • Rate of 330/wk will complete production by 12/31/03

  7. Argonne Checkout • MINDERS, MASTERS, KEEPERS • Minders loaded with MENUs • Full system tests • Dave Reyna: Pedestals, DC Calibration • Tests virtually all aspects of the entire system • Lower Level Testing • Gary Drake, Bill Haberichter, Tim Cundiff, et al. • Testing all bits, reading/writing all registers, etc • Checkout done with a few sets of PROMs • Final PROMs will be burned post-CALDET • Shipping for CALDET in progress

  8. 2003 CALDET Run • Sept. 4 – Oct. 4, 2003 • 1440 channels on Near Detector Electronics • Full instrumentation of 1 side (actual ND is one sided) • Near only, and Near/Far running • Production calibration of Near response • ND Electronics is principle focus of run • Ship electronics in late June • L3 milestone 7/7/03 • Move to beam enclosure 8/18/03

  9. Near Detector Electronics Status All modules have CALDET quantities met Spares (~10%) not included in this table. Various Auxillary cards not included

  10. Summary • Near Electronics Production is Well Underway • All boards in assembly (or done!) • CALDET quantities are met • Thorough Checkout in progress at Argonne, FNAL • IIT help on MENU checkout • Production appears well on schedule for detector installation
